Active clinical trials for "Hepatitis C, Chronic"

The purpose of this study is to assess the efficacy and safety of grazoprevir (MK-5172) 100 mg in combination with elbasvir (MK-8742) 50 mg in the treatment of chronic hepatitis C virus (HCV) in participants who are co-infected with human immunodeficiency virus (HIV). The primary hypothesis is that the percentage of participants who receive grazoprevir + elbasvir and achieve Sustained Virologic Response after 12 weeks of therapy (SVR12) will be greater than 70%.

This is a two-part study of grazoprevir (MK-5172) + elbasvir (MK-8742) in Japanese participants with chronic hepatitis C virus (HCV) genotype 1 (GT1). Part I is a dose-finding study; in Part II, participants will be randomly assigned to receive grazoprevir at the dose determined in Part I in combination with elbasvir. The primary study hypothesis is that the percentage of treatment-naïve participants in the Immediate Treatment Arm of Part II who achieve sustained viral response at 12 weeks after the end of all treatment (SVR12) will be greater than the reference rate of 75%. A separate study arm for cirrhotic participants will also be included in Part II; these participants will receive grazoprevir at the determined dose in combination with elbasvir.

This open-label study will evaluate safety, pharmacokinetics and efficacy of a 12 or 24-week regimen of ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin in HCV-genotype 1-infected subjects with an Estimated Glomerular Filtration Rate (eGFR) <30, including those on hemodialysis or peritoneal dialysis.

The purpose of this study was to investigate antiviral activity, safety and pharmacokinetics of 5 days of monotherapy with BI 207127 in HCV genotype 1 (GT1) infected patients. Both treatment-naïve patients and patients previously treated with peginterferon and ribavirin were included. In addition, the effect of study medication was examined in a group of patients with liver cirrhosis.

The purpose of this study is to demonstrate that the proportion of treatment-naive non-cirrhotic subjects with Genotype (GT)-1b treated with Daclatasvir (DCV)/Asunaprevir (ASV)/BMS-791325 who achieve Sustained Virologic response (SVR12), defined as Hepatitis C virus (HCV) RNA < LOQ target detected or target not detected (LOQ TD/TND) at follow-up Week 12, is significantly higher than SVR12 of current Standard of Care (SOC).

The protocol will study the safety and efficacy of using sofosbuvir and ribavirin for the treatment of hepatitis c in patients taking stribild.

The purpose of this study is to evaluate the efficacy and safety of TMC435 in combination with peginterferon alfa-2a (PegIFNα-2a) and ribavirin in genotype 1 hepatitis C virus (HCV)-infected participants who failed to respond to previous interferon (IFN)-based therapy in Japan.

This phase 2b study will evaluate the efficacy and safety of 16 and 24 weeks of response-guided duration of therapy with GS-9190 and GS-9256 in combination with Peginterferon Alfa-2a (Pegasys®) and Ribavirin (Copegus®). Additionally, the efficacy and safety of 24 weeks of GS-9256 in combination with Peginterferon Alfa-2a (Pegasys®) and Ribavirin (Copegus®) will be evaluated.

Patients with HCV genotype 6 infection who have a rapid virological response to treatment are randomised to either 24 or 48 weeks HCV treatment. Our hypothesis is that there is no important difference in effect between the two treatment effect.

Genotype 4 hepatitis C virus is the cause of approximately 20% of the 170 million cases of chronic hepatitis C in the world. Although rare in western nations, genotype 4 is the most common variant of the hepatitis C virus in Egypt and is also found throughout Africa and the Middle East. Early reports on the treatment of patients with genotype 4 chronic hepatitis C with interferon-alfa (IFN)-alfa monotherapy indicate poor rates of sustained viral response (SVR). With the introduction of ribavirin combination therapy and with pegylation of the IFN alfa molecule, however, response rates have improved dramatically, and current clinical trial data indicate that SVR rates between 43 and 79% are attainable in genotype 4 patients who are receiving pegylated IFN alfa plus ribavirin for 48 weeks. Clinical advances to optimize treatment for each patient have also been made, and tailored treatment options are now being developed that are comparable to the treatment approaches for genotype 1, 2, and 3 patients. A treatment duration of between 36 and 48 weeks appears to be optimal for most patients with chronic hepatitis C genotype 4.The aim of this study is to assess the efficacy and safety of pegylated interferon alpha 2a in patients with chronic hepatitis C genotype 4 in comparison to a historical cohort of patients treated with pegylated interferon alpha 2b
